How can I implement Auth0 authentication in a Vue 3 app using Vuex?

To implement Auth0 in a Vue 3 app with Vuex, you'll need to set up Auth0, install the necessary packages, and configure Vuex to manage authentication state.

What packages do I need to install for this?

You need to install @auth0/auth0-spa-js for Auth0 integration and vuex for state management.

Can you provide a code example for the Vuex store?

Sure! Here's a basic example of a Vuex store that handles authentication state:

import Vue from 'vue';
import Vuex from 'vuex';
import createAuth0Client from '@auth0/auth0-spa-js';

Vue.use(Vuex);

const store = new Vuex.Store({
  state: {
    isAuthenticated: false,
    user: null,
  },
  mutations: {
    setAuthenticated(state, status) {
      state.isAuthenticated = status;
    },
    setUser(state, user) {
      state.user = user;
    },
  },
  actions: {
    async login({ commit }) {
      const auth0 = await createAuth0Client({
        domain: 'YOUR_DOMAIN',
        client_id: 'YOUR_CLIENT_ID',
      });
      await auth0.loginWithRedirect();
      commit('setAuthenticated', true);
    },
    async fetchUser({ commit }) {
      const auth0 = await createAuth0Client({
        domain: 'YOUR_DOMAIN',
        client_id: 'YOUR_CLIENT_ID',
      });
      const user = await auth0.getUser();
      commit('setUser', user);
    },
  },
});

Make sure to replace YOUR_DOMAIN and YOUR_CLIENT_ID with your actual Auth0 credentials.

What about handling logout?

You can add a logout action in your Vuex store like this:

async logout({ commit }) {
  const auth0 = await createAuth0Client({
    domain: 'YOUR_DOMAIN',
    client_id: 'YOUR_CLIENT_ID',
  });
  await auth0.logout({ returnTo: window.location.origin });
  commit('setAuthenticated', false);
  commit('setUser', null);
}
